    Abstract: The invention relates to a method for producing 4-vinylcyclohexene comprising the following steps: (A) a feed gas stream containing n-butane is prepared; (B) said feed gas stream containing n-butane is fed to at least one dehydrogenation zone, where it is dehydrogenated from n-butane to butadiene, whereby a butadiene, n-butane, optionally 1-butene and 2-butene and optionally water vapour and a product stream containing additional minor constituents are obtained; (C) the product stream from the dehydrogenation, optionally after separation of the water vapour and minor constituents, is fed to a dimerization zone, where the butadiene is catalytically dimerized to obtain 4-vinylcyclohexene, n-butane and optionally 1-butene, 2-butene and a product stream containing butadiene that has not been converted; (D) the 4-vinylcyclohexene from the dimerization product stream is separated and the n-butane and optionally 1-butene, 2-butene and the butadiene that has not been converted are returned to the dehydrogenation zone.
